Zoellner illusion. The vertical lines are parallel but seem to be tilted. There are 2 theories as to why this is the case. The first is that the small crossing lines create a perception of depth and our brain's interpretation of perspective leads to the illusion. The second is that the effect is a result of our visual system's propensity to try to minimise acute angles - applied to the small crossing lines.
